Description
Those seeking to lead a spiritual life inevitably face challenges in their pursuit of spirituality and practice. As spiritual development progresses, facing one’s faults, failures, and unintentional mistakes can become disconcerting – even for the most sincere seeker.
One may then ask, “What are the benefits of the different types of religion? From the many religions of the world, which practices will accelerate my spiritual growth and help me learn how to become more spiritual?”
While exploring world religion, or studying religious books, questions might also arise, such as:
“In actuality, what is religion, or what is spirituality? Is it to live in non violence, to live in peace, or to embody unconditional love? How to live exactly?”
In the book “The Essence of All Religion”, Gnani Purush (embodiment of Self knowledge) Dada Bhagwan clarifies any confusion about religion vs. spirituality, providing answers to the above questions and more.
Dadashri then offers the essential extract of spiritual science and religion in the form of Nine Kalams (highest spiritual intents). He explains that the Nine Kalams are the essence of the highest teaching of the religions of the world and the simplest, most direct means to live in peace.
Among the many spiritual books available today, the spiritual guidance available in this book is both unique and unparalleled.
